Changzhou textile printing and dyeing industry advantages and environmental governance how to co-exi

On September 16, in the wastewater recovery control room of Changzhou Xurong Knitting and Dyeing Co., Ltd., water treatment operators are monitoring the treatment process through a computer screen. He told reporters that it mainly depends on the PH value in the storage tank and the COD value in all the sewage tanks, as well as the dissolved oxygen value. “ once the data exceed the standard, the online monitoring system will be displayed immediately to facilitate timely adjustment and control. ”
The reporter saw on the spot that the printing and dyeing wastewater discharged from the printing and dyeing workshop can be directly used by the dyeing workshop through biochemical treatment, ultrafiltration and reverse osmosis treatment, forming a production water recycling and reuse. According to the monitoring system data, the sewage treatment facility can use 1100 tons of reclaimed water for workshop every day.
Xurong knitting deputy general manager Zhang Guocheng told reporters that since 2014, the company has invested more than 30 million yuan to complete the first phase of sewage treatment and reuse facilities, flue gas purification transformation of stereotyping machines, and waste gas treatment facilities transformation of sewage stations. It was put into operation in January 2015 and can reduce 300,000 tons of sewage discharge per year. At present, the company will invest 20 million yuan in the construction of the second phase of reclaimed water reuse project, increase end-treatment efforts to reduce pollutant emissions. Xurong Knitting was listed as the first water efficiency leader in the province in November last year, and was named Green Factory by the Ministry of Industry and Information Technology on January 18 this year, said Zhang Guocheng.
Xu Rong knitting is only a microcosm of our textile dyeing and garment industry. According to the relevant person in charge of the Municipal Economic and Credit Commission, Changzhou is one of the important textile and apparel production bases in China. It has formed eight categories of cotton textiles, printing and dyeing, wool textiles, dyeing and weaving, chemical fibers, knitting, spinning machines and apparel. It has created a large number of subdivisions with high technology, excellent quality, good management and famous brand. Small giant enterprises, such as black peony, Xurong knitting, Qiangsheng textile, Isda textile and other core backbone enterprises. According to statistics, in 2017, the total industrial output value of enterprises in our city was 1267.168 billion yuan, of which the total industrial output value of textile and garment enterprises was 101.025 billion yuan, accounting for 7.97%; the total export value was 1554.8 billion yuan, of which the total export value of textile products was 270.86 billion yuan, accounting for 17.42%. In 2017, the number of textile and apparel enterprises was 502, accounting for 12.1%, and the number of employees was more than 100,000. Our textile and apparel industry has a strong industrial foundation superiority over other industries, and it is still our traditional superior industry.
“ printing and dyeing water is not terrible, the key is governance. At present, we have achieved over 50% emission reduction. Textile printing and dyeing is a high-tech industry. We should rationally plan and lay out the future development of textile printing and dyeing industry. We should let confident and thoughtful enterprises seek greater development and promote green development while winning the battle of pollution prevention and control. We are confident that this industry will become an industrial tourism project in the textile printing and dyeing industry. ” Yun Fang, chairman of Changzhou East Star dyeing and Weaving Co., Ltd., told reporters. On September 15, the Municipal Institute of Textile Engineering convened Xurong Knitting, Qiangsheng Textile, East Asia Science and Technology, Eastern Isda and other enterprises to make suggestions on the special development planning of textile printing and dyeing industry: to make full use of high-quality stock resources, avoid duplicate investment; to formulate practical industry standards, actively guide and encourage textile printing and dyeing industry. Industry healthy, environmental protection, legal and compliance development; formulate special development plan for textile printing and dyeing industry in Changzhou, shut down and transfer or eliminate backward production capacity, etc.
How can industrial advantages and environmental governance co-exist? The Regulations on the Prevention and Control of Water Pollution in Taihu Lake of Jiangsu Province (2018 edition) came into effect on May 1, this year, bringing opportunities and challenges to the green development and high-quality development of strategic emerging industries and printing and dyeing industries in the second and third protected areas of Taihu Lake Basin.
Relevant person in charge of the Municipal Environmental Protection Bureau told reporters that the main pollutants in textile printing and dyeing industry are wastewater, solid waste and exhaust gas. Solid waste mainly relies on third-party units for treatment, and the waste gas is mainly treated by enterprises'self-built pollution prevention facilities. Wastewater treatment, printing and dyeing enterprises in the park through their own sewage station pretreatment take over to the park supporting professional sewage treatment plant for treatment, most of the enterprises outside the park through their own pretreatment take over to the adjacent urban or township sewage treatment plants. At present, there are six auxiliary sewage treatment plants in the printing and dyeing industrial park of our city, such as the sewage treatment plant of Changzhou Textile Industrial Park. The sewage treatment design capacity is 168,000 tons per day. The average wastewater discharge in the textile printing and dyeing industry is 38 million 700 thousand tons / year, accounting for 29% of the total industrial wastewater. The annual output of printing and dyeing sludge in our city is about 214 thousand and 600 tons, accounting for 39 of the total solid waste sludge produced in the city.8%, mainly through six printing and dyeing sludge disposal units such as New Green Sludge Incineration Thermal Energy Co., Ltd., with the thermal power plant mixed firing as the main, brick making, ceramics and other auxiliary disposal. As for the exhaust gas, it mainly comes from the waste gas of wool burner, stereotype machine and sewage treatment station. After the comprehensive implementation of centralized heating and self-built waste gas pollution prevention and control facilities, air pollution has been basically effectively controlled.
At present, there are some problems in some enterprises, such as unreasonable spatial layout, backward technology and equipment, and relatively backward environmental protection measures. The environmental protection department said that we should pay attention to supervision and service at one hand, improve scientific management accurately, further improve the level of classification guidance and service, and avoid ldquo; one-size-fits-all rdquo shutdown and shutdown, so as to promote cleaner production and complete ldquo; green rdquo; technological transformation and effective implementation of ultra-low emission enterprise production limits. To treat it, let the enterprises willing to invest in environmental protection governance taste the sweet end, and inject green gene and green power into the development of enterprises.
In order to speed up the high-quality development of textile printing and dyeing enterprises, the Municipal Development and Reform Commission, the Economic and Credit Commission and the Environmental Protection Bureau are making efforts to accelerate the implementation of five measures:
First, organize the development of textile printing and dyeing industry development special plan. In accordance with the relevant spirit of the provincial environmental protection commission, we should make overall plans for the development of the textile printing and dyeing industry in the city, clarify the development direction, formulate the city-wide-ldquo, the special-purpose-rdquo for the development of textile printing and dyeing industry, and simultaneously compile the environmental impact report of the planning, so as to enable enterprises to enjoy the policy dividend as soon as possible.
Two is to improve the location and related procedures in time. According to our city & ldquo; industry development special planning & rdquo; related textile printing and dyeing parks will actively improve the relevant procedures, for the planning of newly established printing and dyeing parks or industrial agglomeration areas to increase printing and dyeing positioning, the park planning and planning environmental assessment will be completed as soon as possible to clear the obstacles for the subsequent printing and dyeing projects.
Three, we should promote the management of emission permits and strictly control the total amount of pollutants discharged. According to the relevant requirements, the printing and dyeing projects that have not obtained the pollutant discharge permit in accordance with the law will be shut down and eliminated. The municipalities under each jurisdiction will promptly urge printing and dyeing enterprises that have not obtained the emission permit to apply for the emission permit as soon as possible and determine the total amount of enterprise emission. For environmental problems, the time limit for rectification is specified in the discharge permit.
The four is multi stakeholder participation in infrastructure construction. By means of direct investment, investment subsidy and operation subsidy, the government and social capital should be guided and supported to participate in the construction of related infrastructure through various channels, so as to make up for the shortcomings of the stable development of textile printing and dyeing industry, to enhance the sludge disposal capacity, to plan ahead the construction of sewage treatment plants and heating facilities, and to strive for environmental infrastructure. The application is synchronized with the textile dyeing and printing project.
Five is to promote the transformation and upgrading of enterprises, and enhance the green development of the industry. We will resolutely eliminate backward printing and dyeing enterprises with small scale and heavy pollution, free up resources such as production capacity and total pollutant discharge for high-quality projects, and make every effort to promote the upgrading and transformation of printing and dyeing enterprises in printing and dyeing parks or gathering areas with printing and dyeing positioning, implement cleaner production and promote green and ecological transformation. While improving product quality and competitiveness of enterprises, energy saving and consumption reduction can be achieved, and pollutant discharge can be reduced. At the same time, we should actively guide existing printing and dyeing enterprises to merge and reorganize, improve the degree of enterprise agglomeration and garden entry rate, realize the replacement of production capacity, concentrate high-quality resources, form scale advantages, and enhance the competitiveness of the whole industry.
Adhering to the concept of green development and accelerating the pace of transformation and upgrading is the development direction of textile printing and dyeing enterprises in our city. Only by seeking benefits from green, motivating innovation, actively promoting green transformation, intelligent transformation and technological transformation, and initiatively assuming the main responsibility of environmental governance, can enterprises take the right path of high-quality development.
